Speaker Test on Xiaomi: what is it and how to use it correctly

If you own a TV, soundbar, or Xiaomi smart speaker, you've probably come across the term Speaker Test, which is a special mode for diagnosing audio systems, which allows you to check the performance of speakers, identify sound problems, and even calibrate the acoustics to suit the characteristics of your room. But what exactly lies behind this name, how to conduct a test and what to do if the device gives an error? In this article, we will analyze everything from basic principles to advanced settings.

It is important to understand that Speaker Test on Xiaomi devices is not just a check “works / does not work”, it is a comprehensive tool that analyzes the frequency characteristics of speakers, phasing (synchronous operation of several speakers), volume level and even the presence of distortion. For example, on Mi TVs. TV Q2 or Redmi Smart TV The X test can reveal a problem with one of the built-in speakers that you didn't notice when you were watching normally. And in Xiaomi Soundbar soundbars, it helps you adjust the optimal sound for movies or music.

But there's a nuance: Not all models support advanced diagnostics, and in some cases, the test can give false positives — for example, if the speaker is silenced by furniture or there is a high noise level in the room, we will tell you how to avoid errors and what to do if the test showed a problem where there is no such problem.

What is Speaker Test and Why You Need It

Speaker Test (or “Speakers Test”) is a built-in audio diagnostics feature that is available on most Xiaomi devices with speakers: TVs, soundbars, Xiaomi Smart Speaker, and even some smartphones.

• 🔊 Performance check – determines whether all speakers in the system are working (for example, in TVs with support for Dolby Atmos, the subwoofer, front and rear speakers are tested separately).
• 📊 Frequency range analysis – detects dips or peaks at certain frequencies (for example, the absence of bass or wheezing on high notes).
• 🔄 Sound calibration – automatically adjusts the equalizer to the acoustics of the room (available in models with support for Mi Sound Calibration).
• 🚨 Diagnostics of hardware faults – detects problems with the connection of speakers, damage to membranes or problems in the amplifier.

For example, in the TV Xiaomi Mi TV P1 Or the Redmi Max 98 test can show that one speaker is quieter than the others, a sign of either mechanical damage or a problem with soldered contacts. 3.1ch The test checks the synchronization between the main unit and the wireless subwoofer: if the delay exceeds 15 ms, the sound will be smeared".

Important: Speaker Test is not a substitute for professional diagnostics, but it helps to identify obvious problems before contacting the service. For example, if the test shows that the speaker does not make sound at all, the cause may be both a software failure and a physical failure, such as a wire break or an amplifier failure.

What Xiaomi devices are available for Speaker Test

Speaker Test is not available on all Xiaomi devices, but only on those where the manufacturer has provided diagnostic tools for the audio system. Here is the full list of supported categories and models (current for 2026):

Note: on budget models (e.g. Redmi Smart) TV A32 Or Xiaomi Soundbar Basic, the test can be simplified, without frequency analysis, only basic "sound is / no" check, and in flagship devices (for example, Mi). TV Q2 75) Extended options are available, including room acoustic calibration.

It may also be missing from older firmware, such as Mi TVs. TV 4S (2019 Speaker Test only came after the update to MIUI TV 3.0. If your device does not have this option, check the relevance of the firmware in the Settings section. → On TV. → Updating the system.

⚠️ Note: Some Xiaomi smartphones (e.g. Redmi) 10C) The speaker test is run through the engineering menu, but the wrong actions there can lead to a reset or even locking the device.

How to run Speaker Test on Xiaomi TVs

The procedure for running the speaker test on Xiaomi TVs depends on the model and firmware version.We will look at the universal method that works on most devices (including Mi). TV Q1/Q2, Redmi Smart TV X and others, and alternative methods for older models.

Standard method (via the settings menu):

1. Turn on the TV and go to the main menu by pressing the Home button on the remote.
2. Open the settings (cog icon).
3. Select the System section → Diagnostics (or Service Functions on Older Versions).
4. Find the Speaker Test and confirm the launch.

After that, the TV will consistently play the test signals through each speaker (left, right, subwoofer, if any) Your task is to listen and confirm whether the sound is heard. If the speaker does not work, the system will offer options (for example, reboot or reset the audio settings).

Make sure the TV is connected to 220V (not running on backup power)|

Turn off all external audio devices (soundbars, headphones)|

Set the volume to the level. 50-70% precise-test|

Close windows and doors to minimize external noise

-->

Alternative method (via the service menu):

If your model does not have a Diagnostics item, try the following method (works on Mi). TV 4A/4S similar):

1. On the remote, press sequentially: Menu → Settings → All settings → The device → On TV.
2. Find the Model line and quickly click on it 5 times in a row (as when you turn on the developer mode in Android).
3. A hidden menu will open where you need to select Factory Test → Speaker Test.

Be careful: there are options on the service menu that can reset your TV settings or even block it. Don't change settings unless you're sure they're there.

💡

If the TV doesn't respond to remote commands during the test, try using the Mi Remote app on your smartphone. Sometimes reconnecting the remote helps (click the Home buttons). + Back to 5 seconds).

Speaker Test results: What errors mean

After the test is completed, the Xiaomi TV or speaker will display the results, which can be of three types:

• ✅ OK (Passed – the speaker is working normally, no problems detected.
• ⚠️ Warning – there are minor deviations (such as low volume or slight distortions).
• ❌ Failed – the speaker is faulty or not working completely.

Let’s take a closer look at what each status may mean and how to proceed.

1. Failed status (failure)

If the test showed Failed for one or more speakers, the reasons may be as follows:

• 🔌 Connection problems - the plume or connector has gone (relevant for soundbars with an external subwoofer).
• 🔊 Mechanical damage – a speaker membrane is torn or a magnet is damaged.
• 🔋 Amplifier malfunction – a transistor or chip burned in an audio track.
• 📱 Software failure – a firmware error that blocks the output of sound to a certain channel.

What to do:

1. Reboot the device (turn it off for 1 minute).
2. Check physical connections (cables, connectors).
3. Reset the sound settings to factory (Settings) → Sound. → Reset).
4. If nothing helps, contact the service center (especially if the device is warranty).

Warning status (warning)

A warning usually means that the speaker is working, but with deviations.

• 📉 Low volume – the speaker sounds quieter than the others (maybe the grille is clogged or the amplifier problem).
• 🎛️ Distortions at certain frequencies - wheezing on high notes or "blowing" on bass (may be due to equalizer settings).
• 🔄 Unsynchronized channels – delay between left and right speaker (relevant for soundbars).

Decisions:

• Clean the speakers of dust (use a soft brush or vacuum cleaner at minimum power).
• Reset the equalizer settings (Settings) → Sound. → equalizer → Reset).
• Update the device’s firmware (sometimes fixes channel synchronization issues).

3. Status "OK" (It's okay)

If the test was successful, but you still notice problems with sound (such as quiet bass or muted high frequencies), the reasons may be external:

• 🏠 Acoustics of the room – sound is reflected from the walls or absorbed by furniture.
• 🔊 Incorrect settings – the “Night” or “Voice” mode is enabled, which cuts down low frequencies.
• 📺 Signal source – some channels or streaming services transmit audio in compressed format (e.g. Dolby Digital 2.0 instead of 5.1).

Decisions:

• Use the built-in sound calibration (if any in the settings).
• Check the audio output settings on sources (for example, on Netflix or YouTube, select 5.1 or Atmos format if supported).
• Experiment with the position of the device - sometimes rearrange the soundbar 20-30 cm improves sound.

Speaker Test on Xiaomi soundbars and speakers: features

In soundbars and smart speakers, the Xiaomi Speaker Test works a little differently than in TVs.

1. Automatic calibration – many models (e.g. Xiaomi Soundbar) 3.1ch) Not only do they check the speakers, they also tune the sound to the acoustics of the room, and they do that by playing the test signals and analyzing the reflected sound with a built-in microphone.
2. Wireless Connection Checking – In systems with subwoofers or rear speakers, the test diagnoses delays and packet loss over Wi-Fi or Bluetooth.
3. Voice control – in smart speakers (such as Xiaomi Smart Speaker), the test can be run by voice command: “Run sound diagnostics”.

How to run a test on the soundbar Xiaomi Soundbar:

1. Press and hold the Source button on the remote (or device body) for 5 seconds.
2. In the menu, select System Test. → Speaker Check.
3. Confirm the start of the test – the soundbar will play the signals alternately through each speaker.

If the soundbar is connected to the TV through HDMI ARC, The test can also check the synchronization of sound with the image. Normal latency should not exceed 40 ms - if more, turn on the Lipsinc option in the settings of the TV (Sync Audio).

Features of the test for smart speakers Xiaomi Smart Speaker:

• The test checks not only speakers, but also microphones (important for a voice assistant).
• If the column is connected to Mi Home, the test results can be seen in the app in the Device section. → Diagnostics.
• In some models (e.g. Redmi Sonorous), the test starts automatically when it is first turned on.

⚠️ Note: In Xiaomi soundbars with Dolby Atmos support (for example, Mi). TV Soundbar Pro test can take up to 2-3 - Do not interrupt the process, as this can cause a malfunction of the decoder.

Frequent problems and their solutions

Even if the Speaker Test showed that everything is fine, Xiaomi users sometimes have problems with sound, and we collected the most common cases and ways to fix them.

1.The test is successful, but there is no sound

If the speakers are working, but the sound is not played:

• 🔇 Check if the sound is turned off on the remote or in the settings (Settings) → Sound. → Loudness).
• 🔌 Make sure the correct signal source is selected (e.g, HDMI, Not Optical).
• 📱 Reboot the source device (such as a console or smartphone) if the sound is on Bluetooth or HDMI.
• 🔄 Reset the sound settings to factory.

2.The test shows an error, but the sound is

This may be due to:

• 📶 Interference – if other wireless devices are working nearby (router, microwave).
• 🔊 Incorrect calibration – for example, the settings indicate that the subwoofer is connected, but it is not.
• 📱 Firmware failure – helps update or reset.

Solution: Run the test elsewhere (e.g., transfer the soundbar to another room) or reset the settings.

3.The test is suspended or not completed

If the diagnosis process is “locked”:

• 🔌 Turn the device off the network for 1 minute, then turn it on again.
• 📱 Update your firmware via Mi Home or Settings → Update.
• 🔄 If the problem repeats, reset to factory settings (Settings) → System system → Reset).

💡

If you have a problem after resetting, it's a sign of a hardware malfunction. Don't try to repair yourself, call a service center, especially if the device is warranty-free.

4. Different loudness of speakers

If one speaker sounds quieter than the other:

• 🧹 Clean the speaker grilles from dust.
• 🔧 Check the sound balance in the settings (Settings) → Sound. → Balance).
• 🔄 Start the sound calibration again (if you have this option).

If nothing helps, the amplifier of one of the channels may not work, and repairs will be required.
